Innovation Solution

A modular fluid pump system with a universal pump console that recognizes interchangeable pump cassettes through sensors, adjusting motor parameters and display settings based on cassette identifiers to provide the appropriate pumping mechanism for different surgical specialties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple specialized pump systems are used for different surgical specialties, then each specialty receives appropriate fluid pumping capability, but the number of pump consoles increases and operating room space is consumed

Engineering Contradiction:

Improvepump specialty coverageVSAvoidnumber of pump consoles

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pump console is designed with a universal interface that can accept different types of pump cassettes (centrifugal, peristaltic, syringe pumps) through standardized mechanical and electrical connections. The sensor detects cassette identifiers to automatically configure the console for the attached specialty, enabling one console to perform multiple surgical pump functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The pump system is divided into two independent modules: a reusable pump console and disposable/interchangeable pump cassettes. This segmentation allows the console to remain while only the cassette needs to be changed for different specialties, reducing the number of consoles needed while maintaining versatility across surgical disciplines.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a universal pump console accepts multiple pump cassette types, then the number of consoles is reduced, but the system must accurately identify and adapt to different cassette types

Engineering Contradiction:

Improvenumber of pump consolesVSAvoidcassette type identification

Core Design Contradiction:

Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The manual identification and configuration process is replaced with an automated sensor-based detection system. The sensor (optical, magnetic, or RFID) automatically reads the cassette identifier when inserted into the console, eliminating the need for manual setup and reducing errors in cassette type recognition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The pump console automatically configures itself based on the detected cassette identifier. The system self-adjusts motor parameters, pump type settings, and display information without requiring user intervention, making the adaptation process seamless and reducing the difficulty of managing multiple cassette types.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the pump console automatically adjusts motor parameters based on cassette identifier, then the ease of operation is improved, but the sensor detection system adds complexity to the console

Engineering Contradiction:

Improvepump setup and configurationVSAvoidsensor and detection system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pump cassettes are designed as disposable or single-use components that include integrated identifiers. This allows the use of simple, cost-effective sensor systems (optical sensors, magnets, RFID tags) in the reusable console, as each inexpensive cassette provides its own identification information without requiring complex persistent storage or programming in the console.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
